Technologies, methods, and devices known to those of ordinary skill in related arts may not be discussed in detail, but where appropriate, the techniques, the methods, and the devices should be considered as a part of the specification.

In all examples shown and discussed herein, any specific value should be construed as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

It should be noted that like numerals and letters denote like terms in the following drawings. Therefore, once an item is defined in one accompanying drawing, the item does not need to be further discussed in the subsequent accompanying drawings.

The following first specifically describes an electronic-cigarette vaporization device 100 according to embodiments of the present disclosure in conjunction with the accompanying drawings.

As shown in FIG. 1 to FIG. 9 , an electronic-cigarette vaporization device 100 according to an embodiment of the present disclosure includes a housing 10, a vaporization component 20, and a first bracket 30.

Specifically, the housing 10 includes an e-liquid storage bin 11 arranged therein, and the housing 10 is provided with an airflow passage 12 communicated with outside air. The vaporization component 20 includes an e-liquid absorption body 21 and a heating element 22. The heating element 22 is arranged on the e-liquid absorption body 21. The e-liquid absorption body 21 is communicated with the e-liquid storage bin 11. The first bracket 30 is arranged in the housing 10. The vaporization component 20 is arranged on the first bracket 30. The first bracket 30 is provided with a first air guide hole 31 communicated with the airflow passage 12. A barrier portion 32 is arranged on an inner wall of the first bracket 30. The barrier portion 32 corresponds to a position of the first air guide hole 31 to change an airflow direction of air passing through the first air guide hole 31.

In other words, referring to FIG. 1 and FIG. 2 , the electronic-cigarette vaporization device 100 according to the embodiment of the present disclosure is mainly composed of the housing 10 the vaporization component 20, and the first bracket 30. The housing 10 serves as an e-liquid cup of the electronic-cigarette vaporization device 100, the e-liquid storage bin 11 is arranged in the housing 10 (as shown in FIG. 1 to FIG. 3 ), and the e-liquid storage bin 11 is configured to store an e-liquid. The housing 10 is provided with the airflow passage 12. The airflow passage 12 is communicated with outside air. An aerosol generated through vaporization of the e-liquid by the outside air and the vaporization component 20 may enter a user's mouth through the airflow passage 12, for the user to inhale.

The vaporization component 20 is mainly composed of the e-liquid absorption body 21 and the heating element 22. The heating element 22 is arranged on the e-liquid absorption body 21. The e-liquid absorption body 21 is communicated with the e-liquid storage bin 11. The e-liquid in the e-liquid storage bin 11 may penetrate into the e-liquid absorption body 21, and the e-liquid absorption body 21 adsorbs the e-liquid until a saturated state is reached. The heating element 22 can heat the e-liquid absorption body 21 impregnated with the e-liquid, to vaporize the e-liquid into the aerosol. When the user vapes the electronic-cigarette vaporization device 100, the heating element 22 heats the e-liquid absorption body 21 impregnated with the e-liquid, to vaporize the e-liquid into the aerosol. The generated aerosol is finally supplied into the user's mouth through the airflow passage 12.

Referring to FIG. 1 and FIG. 2 , the first bracket 30 is mounted in the housing 10, the vaporization component 20 is arranged on the first bracket 30, and the first air guide hole 31 and the barrier portion 32 are arranged on the first bracket 30. The first air guide hole 31 is communicated with the airflow passage 12, and the barrier portion 32 corresponds to the position of the first air guide hole 31. Referring to FIG. 3 and FIG. 5 , the barrier portion 32 is arranged on an air transfer path of the first air guide hole 31. When the user vapes the electronic-cigarette vaporization device 100, the outside air is introduced through the first air guide hole 31, and collides with the barrier portion 32 after passing through the first air guide hole 31. The barrier portion 32 can prevent the air from flowing upward directly through the first air guide hole 31, increase the resistance to vaping, and provide a buffering function and a function of changing the flow direction of the air. After the air entering the first air guide hole 31 collides with the barrier portion 32, the flow of the air is slowed down and the direction of the air is changed (the transfer direction of the air is denoted by arrows in FIG. 3 and FIG. 5 ). After the transfer direction is changed, the air enters the first bracket 30, fully contacts with the vaporization component 20 to take away the aerosol generated through vaporization by the vaporization component 20, and finally enters the user's mouth, thereby greatly improving the taste of the aerosol for the user.

In addition, when the e-liquid falls from the e-liquid absorption body 21 impregnated with the e-liquid, the e-liquid falls on a bottom wall 33 of the first bracket 30, to prevent the e-liquid from directly flowing out of the electronic-cigarette vaporization device 100 and prevent the electronic-cigarette vaporization device 100 from e-liquid leakage to affect user experience.

It should be noted that in the electronic-cigarette vaporization device 100 of the present disclosure, the e-liquid in the e-liquid storage bin 11 may penetrate into the e-liquid absorption body 21, and the e-liquid absorption body 21 adsorbs the e-liquid until the e-liquid absorption body 21 reaches the saturated state. When a user vapes the electronic-cigarette vaporization device 100, the e-liquid absorbed by the e-liquid absorption body 21 is heated and vaporized by the heating element 22 to generate an aerosol. In addition, as the e-liquid absorbed by the e-liquid absorption body 21 is continuously consumed and vaporized, the e-liquid in the e-liquid storage bin 11 can continuously penetrate into the e-liquid absorption body 21 to meet the vaping demand of the user. During vaping by the user, outside air may be introduced through the first air guide hole 31, collides with the barrier portion 32, and then enters the first bracket 30. The air entering the first bracket 30 fully contacts with the vaporization component 20 to take away the aerosol generated through vaporization by the vaporization component 20, and finally enters the user's mouth, thereby greatly improving the taste of the aerosol for the user.

Therefore, in the electronic-cigarette vaporization device 100 according to the embodiment of the present disclosure, the first air guide hole 31 communicated with the airflow passage 12 is arranged on the first bracket 30, the barrier portion 32 is arranged on the inner wall of the first bracket 30, and the barrier portion 32 is arranged on the air transfer path of the first air guide hole 31. With the arrangement of the barrier portion 32 on the air transfer path of the first air guide hole 31, when outside air is introduced through the first air guide hole 31, the air collides with the barrier portion 32, to improve the flow rate and resistance of air and change the transfer direction of air, thereby ensuring that air fully contacts with the vaporization component 20 impregnated with the e-liquid for vaporization to take away the aerosol, and greatly improving user experience. In addition, when a small amount of e-liquid falls off the e-liquid absorption body 21, the e-liquid falls on the bottom wall 33 of the first bracket 30, and the bottom wall 33 of the first bracket 30 can block the e-liquid, to prevent the leaked e-liquid from directly flowing out of the electronic-cigarette vaporization device 100 to affect user experience.

According to an embodiment of the present disclosure, the inner wall of the first bracket 30 is defined as a first side wall 34. The first air guide hole 31 is arranged at a joint of the bottom wall 33 of the first bracket 30 and the first side wall 34, the barrier portion 32 is arranged at a position on the first side wall 34 corresponding to the first air guide hole 31, and the barrier portion 32 is located on one side of the first air guide hole 31 facing the e-liquid storage bin 11. The e-liquid absorption body 21 divides the airflow direction of the air passing through the first air guide hole 31 into two airflow directions, and the air in the two airflow directions respectively contacts with two sides of the e-liquid absorption body 21 and is then led out through the airflow passage 12.

In other words, as shown in FIG. 7 to FIG. 9 ; the first air guide hole 31 is provided at the joint of the bottom wall 33 and the first side wall 34 of the first bracket 30, and the first bracket 30 may be a silica gel bracket.

According to an embodiment of the present disclosure, a side surface of the barrier portion 32 facing the vaporization component 20 is defined as a second side wall 35, and the first side wall 34 is arranged opposite to the second side wall 35. The first side wall 34 is an inner wall surface of the first bracket 30 close to the first air guide hole 31. The first air guide hole 31 is communicated with the airflow passage 12, and outside air may be transferred between the first air guide hole 31 and the airflow passage 12. Referring to FIG. 2 and FIG. 4 the barrier portion 32 may be arranged on the first side wall 34, and the barrier portion 32 corresponds to the position of the first air guide hole 31. The introduction of the outside air from the first air guide hole 31 may be understood as that air is transferred along an airflow direction in the first air guide hole 31. The air exiting the first air guide hole 31 collides with the barrier portion 32, so that the transfer direction of the air is changed.

In the present disclosure, air collides with the barrier portion 32 after passing through the first air guide hole 31, and the transfer direction of the air (or airflow direction) is changed after the collision. The e-liquid absorption body 21 divides the airflow direction of the air passing through the first air guide hole 31 into two, i.e., two airflow directions are generated on two sides of the e-liquid absorption body 21. The air in the two airflow directions respectively contacts with two sides of the e-liquid absorption body 21 and is then led out through the airflow passage 12. The airflow directions are denoted by arrows in FIG. 3 and FIG. 5 . After the air contacts with the e-liquid absorption body 21 in the two airflow directions, the air finally enters the user's mouth through the airflow passage 12. Compared with a case where air is introduced into the first bracket 30 along one airflow direction, the air collides with the barrier portion 32 after passing through the first air guide hole 31, thereby improving the air flow rate and resistance and increasing the contact area between the air and the vaporization component 20. In this way, the air entering the first bracket 30 fully contacts with the vaporization component 20, takes away the aerosol generated through vaporization by the vaporization component 20, and enters the user's mouth, thereby greatly improving the taste of the aerosol for the user.

In some specific implementations of the present disclosure, referring to FIG. 2 and FIG. 4 , the first air guide hole 31 runs through the bottom wall 33 along a thickness direction of the bottom wall 33. An upper end of the first air guide hole 31 is communicated with the airflow passage 12, and a lower end of the first air guide hole 31 is communicated with outside air. The outside air is introduced through the first air guide hole 31 and collides with the barrier portion 32. The barrier portion 32 can prevent the air from flowing upward directly through the first air guide hole 31, increase the resistance to vaping, and provide a buffering function and a function of changing the flow direction of the air.

In an embodiment of the present disclosure, referring to FIG. 2 and FIG. 4 , a cross section of the first air guide hole 31 may be rectangular, and the barrier portion 32 is spaced apart from the first air guide hole 31. The barrier portion 32 is located above the first air guide hole 31, so that the air exiting the first air guide hole 31 can collide with the barrier portion 32. Of course, the specific shape of the first air guide hole 31 may be specifically defined according to actual needs and will not be described in detail in the present disclosure.

According to an embodiment of the present disclosure, the barrier portion 32 horizontally extends from the first side wall 34 toward the vaporization component 20.

Referring to FIG. 2 and FIG. 4 , the barrier portion 32 extends toward the vaporization component 20, and the barrier portion 32 is located on the side of the first air guide hole 31 facing the e-liquid storage bin 11, to block the air for collision. According to an embodiment of the present disclosure, the barrier portion 32 horizontally extends toward the vaporization component 20, so that the barrier portion 32 is horizontally arranged above the first air guide hole 31 to ensure that the air can completely collide with the barrier portion 32.

In an embodiment of the present disclosure, a horizontal extending dimension of the barrier portion 32 is smaller than a length dimension of the cross section of the first air guide hole 31. An area of an orthographic projection of the barrier portion 32 on the first air guide hole 31 is smaller than a cross-sectional area of the first air guide hole 31, to optimize the transfer channel of the outside air at the first air guide hole 31.

In some specific implementations of the present disclosure, the length dimension of the cross section of the first air guide hole 31 ranges from 1 mm to 2 mm. A distance between one side of the barrier portion 32 facing the first air guide hole 31 and the first air guide hole 31 in a vertical direction ranges from 0.8 mm to 2.5 mm. A distance between an extension line of one side of the barrier portion 32 close to the second side wall 35 and an extension line of one side of the first air guide hole 31 away from the first side wall 34 in a vertical direction ranges from 0.5 mm to 1.5 mm.

In other words, as shown in FIG. 4 , assuming that the cross section of the first air guide hole 31 is rectangular, and the length dimension of the cross section of the first air guide hole 31 may be defined as d1 and set to ranges from 1 mm to 2 mm. The distance between the barrier portion 32 and the side of the first air guide hole 31 facing the barrier portion 32 may be defined as d2 and set to ranges from 0.8 mm to 2.5 mm. The barrier portion 32 of the present disclosure is similar to a stop wall structure. The distance between the extension line of the side of the barrier portion 32 facing the second side wall 35 of the first bracket 30 and the extension line of the side of the first air guide hole 31 away from the first side wall 34 of the first bracket 30 in the vertical direction is defined as d3 and set to ranges from 0.5 mm to 1.5 mm. With the arrangement of the barrier portion 32 above the first air guide hole 31, the first air guide hole 31 and the barrier portion 32 jointly define a bent passage for leading out the air.

When the user vapes, the air enters from the first air guide hole 31 at the bottom of the first bracket 30. A special stop wall structure (the barrier portion 32) is designed, and the dimensional distance between the barrier portion 32 and the first air guide hole 31 is further optimized. As shown in FIG. 4 , a width d1 of an entrance opening of the internal airway barrier wall is designed to be ranged from 1 mm to 2 mm, an outlet width d3 is designed to be ranged from 0.5 mm to 1.5 mm, and a height d2 is designed to be ranged from 0.8 mm to 2.5 mm. The above dimension ranges allow for optimal collision rebound between the air and the barrier portion 32, so that the air flow rate and resistance can be optimized and improved. Of course, it may be understood by those skilled in the art that any dimensions that allow for optimal collision rebound between the air and the barrier portion 32 fall within the scope of protection of the present disclosure, which will not be described in detail in the present disclosure.

The e-liquid in the e-liquid storage bin 11 may be introduced to two ends of the e-liquid absorption body 21 through the two e-liquid guide holes 42 respectively, thereby improving the e-liquid absorption efficiency of the e-liquid absorption body 21. An air guide path is formed by the air inlet 51, the first air guide hole 31, the second air guide hole 41, and the airflow passage 12, and the e-liquid guide paths are independent of the air guide path.

In the present disclosure, when the e-liquid adsorbed by the e-liquid absorption body 21 reaches saturation and a small amount of e-liquid leaks from an end of the e-liquid absorption body 21, the leaked e-liquid falls on the bottom wall 33 of the first bracket 30, which prevents the falling e-liquid from directly falling onto the air inlet 51 and flowing out of the housing 10, and preventing the electronic-cigarette vaporization device 100 from e-liquid leakage to affect user experience.

In an embodiment of the present disclosure, referring to FIG. 2 , a vaporization chamber 23 is defined between the second bracket 40 and the first bracket 30, the first air guide hole 31 is communicated with the second air guide hole 41, and the vaporization component 20 is arranged in the vaporization chamber 23. During vaping by the user, outside air may be introduced through the first air guide hole 31, collide with the barrier portion 32, and then enter the vaporization chamber 23. The air entering the vaporization chamber 23 fully contacts with the vaporization component 20, takes away the aerosol generated through vaporization by the vaporization component 20, and enters the user's mouth through the airflow passage 12, thereby greatly improving the taste of the aerosol for the user.

When the aerosol condenses in the airflow passage 12 and the generated droplets fall off along a side wall of the airflow passage 12, the droplets fall on the beam 43, thereby preventing the droplets from directly falling on the heating element 22 of the vaporization component 20 to cause e-liquid explosion.

In an embodiment of the present disclosure, the vaporization component 20 is a cotton core vaporizer. The e-liquid absorption body 21 is columnar, and two ends of the e-liquid absorption body 21 respectively abut against the two e-liquid guide holes 42 of the second bracket 40. The heating element 22 is wound on a middle portion of the e-liquid absorption body 21, and an orthographic projection of the beam 43 on the bottom wall 33 of the first bracket 30 covers the e-liquid absorption body 21.

In other words, referring to FIG. 1 , the vaporization component 20 may be a cotton core vaporizer, the e-liquid absorption body 21 may be columnar, and the e-liquid absorption body 21 may be an e-liquid absorption cotton core. The two ends of the e-liquid absorption body 21 respectively abut against the two e-liquid guide holes 42 on the second bracket 40. The e-liquid in the e-liquid storage bin 11 penetrates into the e-liquid absorption body 21 through the two e-liquid guide holes 42 on the second bracket 40, and is absorbed by the e-liquid absorption body 21. The heating element 22 is wound around the e-liquid absorption body 21, and the heating element 22 is substantially wound at a middle portion of the e-liquid absorption body 21. The heating element 22 corresponds to the positions of the second air guide hole 41 and the airflow passage 12, so that the aerosol generated by the heating element 22 by vaporizing the e-liquid can be discharged to the airflow passage 12. An orthographic projection of the beam 43 on the bottom wall 33 of the first bracket 30 covers the e-liquid absorption body 21, the beam 43 is located between the second air guide hole 41 and the e-liquid absorption body 21, and the beam 43 corresponds to the position of the heating element 22 in a length direction of the airflow passage 12. When the aerosol condenses in the airflow passage 12 and the generated droplets fall off along the side wall of the airflow passage 12, the droplets fall on the beam 43, thereby preventing the droplets from directly falling on the heating element 22 to cause e-liquid explosion.

According to an embodiment of the present disclosure, referring to FIG. 1 and FIG. 2 , a central axis of the air inlet 51 and a central axis of the first air guide hole 31 are not in a same straight line. In other words, the air inlet 51 on the cover 50 is staggered from the first air guide hole 31, so as to prevent the e-liquid leaking from the first air guide hole 31 from directly flowing out of the housing 10 through the air inlet 51, and prevent the electronic-cigarette vaporization device 100 from e-liquid leakage to affect user experience.

In the present disclosure, as shown in FIG. 1 , FIG. 2 , and FIG. 6 , the electronic-cigarette vaporization device 100 further includes a second sealing member 72, which may be a sealing ring. The second sealing member 72 is arranged in the housing 10, the second sealing member 72 is sleeved on an outer wall surface of the second bracket 40, and an outer edge of the second sealing member 72 abuts against an inner wall of the housing 10. The e-liquid storage bin 11 may be defined jointly by the second bracket 40, the housing 10, and the second sealing member 72. The arrangement of the second sealing member 72 prevents the e-liquid in the e-liquid storage bin 11 from leaking from the inner wall of the housing 10 to the outside of the housing 10.

In the present disclosure, referring to FIG. 1 , FIG. 2 , and FIG. 6 , the electronic-cigarette vaporization device 100 further includes a third sealing member 73, which may be a sealing ring. The third sealing member 73 is sleeved on an outer wall surface of the cover 50, and an outer edge of the third sealing member 73 abuts against the inner wall of the housing 10. With the arrangement of the third sealing member 73 sleeved on the outer wall surface of the cover 50, a small amount of e-liquid leaking from the second sealing member 72 can further be sealed, to prevent the small amount of e-liquid from leaking from between the cover 50 and the housing 10 to the outside of the housing 10, thereby further improving the overall sealing performance of the electronic-cigarette vaporization device 100.

According to an embodiment of the present disclosure, as shown in FIG. 1 , FIG. 2 , and FIG. 6 , the electronic-cigarette vaporization device 100 further includes a conductive pin 80. A quantity of conductive pins 80 is two. The two conductive pins 80 can pass through the bottom of the cover 50. The conductive pins 80 are electrically connected to the heating element 22 to realize the vaporization of the e-liquid by the vaporization component 20.

In the assembly process of the electronic-cigarette vaporization device 100 of the present disclosure, referring to FIG. 1 and FIG. 6 , the first sealing member 71 may be sleeved on the second bracket 40. The two parts are sealed and fixed by an interference fit. The first sealing member 71 is configured to seal the airflow passage 12 of the housing 10 and the second bracket 40. Then, the second sealing member 72 is sleeved on the second bracket 40. After the second sealing member 72 is sleeved, the two parts are tightened to achieve an assembly fit. The second sealing member 72 is configured to seal the inner wall of the housing 10 and the second bracket 40. The e-liquid storage bin 11 configured to store the e-liquid is defined by the second bracket 40, the second sealing member 72, and the housing 10. The third sealing member 73 is sleeved on the cover 50. The cover 50 is connected to the second bracket 40 and electrically connected to the vaporization component 20 through the conductive pins 80. Finally, the structure obtained by assembling the first bracket 30, the vaporization component 20, the second bracket 40, the first sealing member 71, the second sealing member 72, the cover 50, the third sealing member 73, and the conductive pin 80 is mounted in the housing 10, and is slowly pushed into the housing from one end of the housing 10 until the structure abuts against the airflow passage 12 of the housing 10.

When the user vapes, air enters from the air inlet 51 at the bottom of the housing 10 and then enters the vaporization chamber 23 through the first air guide hole 31 on one side of the first bracket 30. The design of the special inner cavity stop wall structure (barrier portion 32) and dimensions allows for optimal collision rebound between the air and the barrier portion 32, thereby optimizing and improving the air flow rate and resistance to the greatest extent. The width d1 of the cross section of the first air guide hole 31 is designed to be ranged from 1 mm to 2 mm, the outlet width d3 is designed to be ranged from 0.5 mm to 1.5 mm, and the height d2 is designed to be ranged from 0.8 mm to 2.5 mm. When the dimensions are within the dimension ranges, optimal collision rebound is achieved between the air and the barrier portion 32. The air contacts with the cotton core vaporizer (vaporization component 20) impregnated with the e-liquid for vaporization to generate an aerosol. The aerosol continues to flow upward through the two sides of the second bracket 40 to enter the user's mouth.

After the user stops vaping and the air cools down, a condensate is adsorbed on the side wall of the airflow passage 12, and after a period of time, the condensate flows into the airflow passage. The arrangement of the beam 43 exactly below the airflow passage 12 can prevent the condensate from falling directly onto the vaporization component 20 to cause e-liquid explosion or other problems. In addition, with the design of the liquid absorption body 60 (liquid absorption cotton) above the air inlet 51, when a small amount of e-liquid falls off the e-liquid absorption body 21, the e-liquid falls on the bottom wall 33 of the first bracket 30, and the bottom wall 33 of the first bracket 30 can block the e-liquid, to prevent the e-liquid from directly falling on the air inlet 51. The liquid absorption body 60 can absorb the excess e-liquid in time, thereby preventing the e-liquid from flowing out of the housing 10 to affect user experience.

To sum up, in the electronic-cigarette vaporization device 100 according to the embodiment of the present disclosure, the first air guide hole 31 communicated with the airflow passage 12 and the barrier portion 32 are arranged on the first bracket 30, and the beam 43 is arranged below the airflow passage 12. With the arrangement of the barrier portion 32 on the air transfer path of the first air guide hole 31, when outside air is introduced through the first air guide hole 31, the air collides with the barrier portion 32, to improve the flow rate and resistance of air and change the transfer direction of air. In this way, air fully contacts with the vaporization component 20 impregnated with the e-liquid for vaporization to take away the aerosol, thereby greatly improving user experience. The arrangement of the beam 43 can prevent the condensate from falling directly onto the vaporization component 20 to cause e-liquid explosion or other problems. In addition, when a small amount of e-liquid falls off the e-liquid absorption body 21, the e-liquid falls on the bottom wall 33 of the first bracket 30, and the bottom wall 33 of the first bracket 30 can block the e-liquid, to prevent the e-liquid from directly falling on the air inlet 51. The liquid absorption body 60 can absorb the excess e-liquid in time, thereby preventing the e-liquid from flowing out of the housing 10 to affect user experience.
